NAME¶

FFI — Foreign Function Interface

LIBRARY¶

libffi, -lffi

SYNOPSIS¶

#include <ffi.h> ffi_status
ffi_prep_cif(ffi_cif *cif, ffi_abi abi, unsigned int nargs, ffi_type *rtype, ffi_type **atypes); void
ffi_prep_cif_var(ffi_cif *cif, ffi_abi abi, unsigned int nfixedargs, unsigned int ntotalargs, ffi_type *rtype, ffi_type **atypes); void
ffi_call(ffi_cif *cif, void (*fn)(void), void *rvalue, void **avalue);

DESCRIPTION¶

The foreign function interface provides a mechanism by which a function can generate a call to another function at runtime without requiring knowledge of the called function's interface at compile time.
